Draft Findings of Fael and Mitigalion Monitoring Reporting Program (applies 10 CEQA only) AQ-32 During construction, the contractor shall use the following measures to minimize dust: . Cover trucks when transferring materials . Use dust suppressants on traveled paths that are not paved . Minimize unnecessary vehicular and machinery activities . Minimize dirt track-<lut by washing or cleaning trucks before they exit the construction site AQ-43 Post-construction, the contractor shall use the following measures to minimize dust: . Revegetate any disturbed land not used . Remove unused material . Remove dirt piles . Revegetate all vehicular paths created during construction to avoid future off- road vehicular activities With Mitigation the Effects are Found to be: ( ) Significant (x) Not Significant Finding: 1. (x) Changes or alterations have been required in, or incorporated into, the project, which avoid the significant environmental effect. (Subd. [a][l].) 2. () Such changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agency. (Subd. [a][2].) 3. ( ) Specific economic, legal, social, technological, or other considerations, including provision of employment opportunities for highly trained workers, make infeasible the mitigation measures or project alternatives identified in the Final EIR/EA (Subd. [a][3].) Rationale: Implementation of these mitigation measures will reduce air quality impacts to levels less than significant by ensuring that short-term construction-related air pollution is minimized. No further mitigation is required. Reference: The discussion on setting, impacts, and mitigation related to Air Quality are included in Section 4.4 of the FEIR/EA prepared for the Alton Avenue Overcrossing at SR-55. 7.5 NOISE Potentially Significant Effects Permanent Impacts Under the Preferred Alternative, the noise abatement criteria (NAC) would be exceeded at Sites 2 (Adagio Apartment Complex) and 3 (Single-Family Residence at 110 Alton Avenue). For Site 2, the existing noise level is 65 dBA, and the predicted noise level for year 2025 is 69 dBA under Allon Avenue Overerossing at SR-55 K-J9 ResolutlOAP~99 Page 31 of 49
